Presence Orb adheres to Smart Places guidelines. Smart Places is a global opt-out list where any individual can choose to be excluded from data sets by all subscribing businesses. Although this is not required by law in any country, it is considered best practice, and Presence Orb has the data security of clients and consumers at the heart of its security policies. Any individual can opt-out by visiting the Smart Places website and submitting their devices’ MAC addresses - https://optout.smart-places.org/
